1 at the same time. At the same time, multiple program activities may execute the same program on different data sets, so the program and the machine executor's activities no longer have a strict one-to-one correspondence.
2. It provides a variety of functions that enable multiple applications and users to establish, modify and query databases at the same time or at different times in different ways. It enables users to easily define and manipulate data, maintain the security and integrity of data, and carry out concurrent control and recovery of databases under multiple users.
3. [Answer]: D The question clearly indicates that it is a dual-processor computer system. Even if there are 3 concurrent processes at the same time, the maximum number of processes that the dual processor can process is 2.
Four characteristics of the operating system Concurrency: refers to the occurrence of two or more events at the same time interval. The concurrency of the operating system refers to the existence of multiple running programs in the computer system at the same time, so it should have the ability to process and schedule the simultaneous execution of multiple programs.
Concurrency and sharing are the most basic features of the operating system. They are interrelated and promote each other. Concurrency is a prerequisite for the operating system to realize resource sharing, and sharing is the basis for the operating system to achieve concurrency.
Concurrency, sharing, virtuality, asynchronous. Concurrency: refers to two or moreEvents occur at the same time interval. These events occur at the same time at the macro, but alternately at the micro. Parallel: refers to the occurrence of two or more events at the same time.
The basic characteristics of the operating system are four, namely: concurrency, sharing, virtuality, asynchronous concurrency: refers to the occurrence of two or more events at the same time interval, that is, the device executes this event and the file, and multiple events use one device together.
Shareability and concurrency are the two most basic characteristics of the operating system, and they are interdependent.
1. System splitting Split a system into multiple subsystems and use dubbo to do it.Then each system is connected to a database, so that it was originally a library, but now there are multiple databases, so that it can resist high concurrency.
2. We only discuss the high-concurrency snap-up activities of the front-end of technical solutions. The three axes commonly used in the front-end are [capacity expansion] [staticization] [flow limitation] A: capacity expansion plus machine, which is the easiest way to resist peaks by increasing the overall carrying capacity of the front-end pool.
3. Use the message queue method to solve: Message queue is a common method to solve high concurrency problems. Put the user's requests into the message queue, and then process the requests in the queue one by one through the consumer process. This can effectively distribute requests and avoid a large number of requests reaching the database at the same time, resulting in excessive pressure on the database.
1. Concurrency means that the operating system can run multiple applications or tasks at the same time. These applications or tasks can be executed at the same time, but not necessarily at the same time, because the operating system will allocate time slices for each application or task so that they can be executed alternately.
2. The two most basic characteristics of the operating system are concurrency and commonality. Concurrency means that the operating system can handle multiple tasks or operations at the same time. In modern computer systems, concurrency is an important means to improve system efficiency and response speed.
3. The concurrency of the operating system refers to the existence of multiple running programs in the computer system at the same time, so it should have the ability to process and schedule the simultaneous execution of multiple programs.Concurrency requires the support of relevant hardware, such as multi-assembly line or multi-processor hardware environment.
4. Concurrency refers to the occurrence of two or more events at the same time interval. In the multi-program environment, concurrency refers to the simultaneous execution of multiple macro programs within a period of time. In a single-processor system, multiple programs are executed alternately in the microcomputer system; in the multi-processor system, multiple programs are executed in parallel in the micro.
5. The characteristics of the operating system are: concurrency, sharing, virtuality, parallelism, asynchronousness, etc. Concurrency There are multiple independently running programs in the computer system, which can be executed in the same period of time.
